this DCB filter board prevents improper signal modulation and potential system shutdowns due to electrical transients

This is a normally open (NO) assembly

preventing fluid or gas bypass that leads to system inefficiency

it is ideal for high-demand burners and boilers requiring a low-pressure gas solenoid solution

Field Serviceable: The welded element and internal components are accessible for cleaning or inspection

Maxitrol R400Z-1/2-CSA Valve 320788-702 this DCB filter board preventsThe Maxitrol R400Z 1 2 CSA is a specialized zero governor gas regulator engineered for high precision control in proportional air gas mixing systems. This balanced valve regulator is a critical component for industrial burner applications, nozzle mixers, and pre mixers where maintaining a constant atmospheric or sub atmospheric pressure is essential. Designed with a 1 2" NPT connection, the R400Z serves as an adaptable gas pressure regulator capable
